AV-STOR AV-A16F-R2221

The AV-STOR's RAID functionality is unmatched in the industry in terms of its wide variety of array configuration, maintenance, and monitoring capabilities.

The AV-STOR A16F-R2221 has two 2Gbps Fibre host channels that are routed though an onboard hub to four small form-factor pluggable (SFP) ports. The sixteen SATA-II drive channels are routed through the backplane board to the sixteen drives installed in the front panel of the subsystem. The susbsystem combines massive storage capacity with SATA-II benefits, such as high performance and full bandwidthm in a safe environment where the highest level of data availability is assured.

Availability

Almost every major component in the AV-A16F-R2221 subsystem is hot swappable. Two redundant, dual speed, dual fan cooling modules supply sufficient airflow with minimal sound. The two redundnant 460W power supply units provide stable electric power. Additionally, the AV-A16F-R2221 susbsystem is eqipped with two independent host connection modules to ensure data availability and the highest fault tolerant operation even if one channel fails. The AV-A16F-R2221 provides quiet operation with unsurpassed reliability in today's most extreme storage environments.

Serviceability

The redundant controller architecture provides Fibre loops across the backplane for synchronised cache communications. The internal hub not only provides expansion capability but also lowers the total cost of ownership by eliminating the need for expensive Fibre switches when connecting to extrenal host computers. The internal hub can easily be enabled or disabled using the DIP switch on the enclosure configuration card located on the subsystem rear panel. This reliable, SAN-ready susbsystem features a modular design with easy access to all major components, making it easy to service and maintain.

Reliability

An array disaster can be loosely defined as a significatn loss of data availability. This can range from the merely inconvenient to the truly catastrophic where a large corporation is brought to a standstill. The AV-A16F-R2221 is equipped with two battery backup units that provide power to cache memory when power fails. When fully charged, the BBUs can keep the unwritten cached data in cache memory for up to 72 hours. The subsystem further guarantees data safety by supporting installation of an uninterruptible power supply (UPS) which can extend the operating time for the entire subsystem druing a power failure.

Manageability

A variety of management interfaces are available. The array can be accessed through the LCD keypad panel, RS-232C terminal, telnet, or remotely through the Java RAID manager. The RAID manager provides "Install Once, Run Anywhere" convenience with a graphical user interface.

Users are constantly aware and automatically notified of array status using any or all of the following notification methods:-

Guaranteed Latency I/O

Fast return of read requests by generating data from adjacent stripes when a drive fails or bad sectors cause delays

Major Markets and Uses
